With flow sensors you can measure and monitor the flow of process media in a wide variety of applications. For example, the flow of cooling lubricant or the reliable circulation of cooling water. Leaks or the failure of a pump are detected early and unplanned machine or even system downtime is prevented. In this way, flow sensors contribute to process reliability just like pressure or temperature sensors.
